What are common issues when trying to redirect PHP output to a file instead of the browser?

Common issues when trying to redirect PHP output to a file instead of the browser include not properly opening and closing the file handle, not checking if the file can be opened for writing, and not properly writing data to the file. To solve these issues, make sure to open the file with the correct mode for writing, check if the file can be opened successfully, and use functions like fwrite() to write data to the file. 

<?php
// Open the file for writing
$file = fopen('output.txt', 'w');

// Check if the file was opened successfully
if ($file === false) {
    die('Unable to open file for writing');
}

// Redirect output to the file
ob_start();
echo "Hello, world!";
file_put_contents('output.txt', ob_get_clean(), FILE_APPEND);

// Close the file handle
fclose($file);
?>
